TODO:
- Dip switches mapping is not complete. ( Anyone has the manual handy? )
- Missing drums, they might be internal to the YM2608.
- Hook up trackball controls in wc90t.

To enter into input test mode:
-keep pressed one of the start buttons during P.O.S.T.(in wc90 & wc90a).
-keep pressed both start buttons during P.O.S.T. until the cross hatch test fade out(in wc90t).
Press one of the start buttons to exit.

There is known to be a Pacman hack running on this hardware.  It was done by Mike C. and isn't ment
for inclusion in MAME.  However the roms with checksums are listed below to prevent it being added
as a newly "found" game:

Set is known as pac90 (rom names may differ, but the CRC32/SHA1 values are listed):
